Abstract
There is provided a process for the solidification of radioactive boron containing aqueous solutions and suspensions containing more than 5% boric acid or a borate and more than 5% solids by addition of suitable additions in the correct sequence to form solid, transportable and storable blocks by using as the additive first 5 to 30 parts by weight of slaked lime and then 30-80 parts by weight of cement per 100 parts by weight of radioactive solution.
Claims8
A process for the solidification of radioactive boron containing aqueous solutions or suspensions containing more than 5% of boric acid or borate and more than 5% solids to form a solid, transportable, storage stable block by adding suitable compounds in the correct sequence comprising adding to 100 parts by weight of said radioactive solution first 5-30 parts by weight of quick lime and then adding 30 to 80 parts by weight of cement.
